1 Analysis of Samples Collected at Special-Study

ANALYSIS OF SAMPLES COLLECTED AT SPECIAL-STUDY SITES DELAWARE RIVER BASIN NAWQA PROJECT

The National Water-Quality Assessment (NAWQA) Program of the U.S. Geological Survey is a long-term program with goals to describe the status and trends of water-quality conditions for a large, representative part of the Nation’s ground- and surface-water resources; provide an improved understanding of the primary natural and human factors affecting these observed conditions and trends; and provide information that supports development and evaluation of management, regulatory, and monitoring decisions by other agencies.

Assessment activities are being conducted in 53 study units (major watersheds and aquifer systems) that represent a wide range of environmental set- tings nationwide and that account for a large percentage of the Nation’s water use. A wide array of chemical constituents will be measured in ground water, surface water, streambed sediments, and ﬁsh tissues. The coordinated application of comparative hydrologic studies at a wide range of spatial and temporal scales will provide information for decision making by water-resources managers and a foundation for aggregation and comparison of ﬁndings to address water-quality issues of regional and national interest.

NAWQA study units are divided into three groups that are studied intensively on a rotational basis. Three NAWQA studies have been active in the state of Pennsylvania. The Lower Susquehanna (LSUS) study unit conducted intensive sampling from 1993 through 1995 and is currently in a low-intensity phase. The Alleghney and Monongahela River Basins (ALMN) study unit conducted intensive sampling from 1996 through 1998 and is currently in a low-intensity phase. The Delaware River Basin (DELR) study unit started intensive sampling in 1999 and will complete this phase of the study in 2001. It will then enter the low-intensity phase and is scheduled to resume intensive sampling in 2008.

Communication and coordination between USGS personnel and other local, State, and federal interests are critical components of the NAWQA Pro- gram. Each study unit has a local liaison committee consisting of representatives from key federal, State, and local water resources agencies, Indian nations, and universities in the study unit. Liaison committees typically meet semiannually to discuss their information needs, monitoring plans and progress, desired information products, and opportunities to collaborate efforts among the agencies.

Additional information about the NAWQA Program is available through the world wide web at http://water.er.usgs.gov/nawqa/nawqa_home.html.

Analyses of volatile organic compounds in surface-water and ground-water samples (schedule 2020/2021)

Selected surface water samples from DELR-NAWQA study sites were analyzed for volatile organic compounds (VOCs) in water year 2000. The National Water Quality Lab (NWQL) created a method for accurate determination of VOCs in water in the nanogram per liter range, schedules 2020/2021. The method described in USGS Open-File Report 97-829 (Connor and others) is similar to USEPA method 524-2 (Mund, 1995) and the method described by Rose and Schroeder (1995). Minor improvements to instrument operating conditions include the following: additional compounds, quantitation ions that are different from those recommended in USEPA Method 524.2 because of interferences from the additional compounds, and a data reporting strategy for mea- suring detected compounds extrapolated at less than the lowest calibration standard or measured at less than the reporting limit. The minimum reporting limit (MRL) is introduced as a statistically deﬁned reporting limit designed to limit false positives and false negatives to less than 1 percent.

This table lists the volatile organic compounds on the schedule, the unit of measure (micrograms per liter (µg/L), the U.S. Geological Survey National Water Information System parameter code, the Union of Pure and Applied Chemistry (IUPAC) compound name, and the National Water Quality Laboratory compound name. Positive detections measured at less than MRL but greater than or equal to the long-term method-detection limit are reported as estimated concentrations (E) to alert the data user to decreased conﬁdence in accurate quantitation. Values for analytes in the 2020/2021 schedules are preceded by an "E" in the following situations:

1. When the calculated concentration is less than the lowest calibration standard. The analyte meets all identification criteria to be positively identified, but the amount detected is below where it can be reliably quantified. 2. If a sample is diluted for any reason. The method reporting level is multiplied by the dilution factor to obtain the adjusted method reporting level. Values below the lowest calibration standard, multiplied by the dilution factor are qualified with an "E". For example, a value of 0.19 in a 1:2 dilution is reported as E0.1. 3. If the set spike has recoveries out of the specified range (60-140%). 4. If the analyte is also detected in the set blank. If the value in the sample is less than five times the blank value and greater than the blank value plus the long term method detection limit, the value is preceded by an "E" to indicate that the analyte is positively identified but not positively quantified because the analyte was also detected in the blank.

Only VOCs detected for one or more samples are listed in the water-quality tables. 4

ANALYSIS OF SAMPLES COLLECTED AT SPECIAL-STUDY SITES DELAWARE RIVER BASIN NAWQA PROJECT

SCHEDULE DESCRIPTION.--The sample water is actively purged with helium to extract the volatile organic compounds. The volatile compounds are trapped onto a sorbent trap, thermally desorbed, separated by a megabore gas chromatographic capillary column, and finally determined by a full scan quadropole mass spectrometer. Compound identification is confirmed by the gas chromatographic retention time and by the resultant mass spectrum, typically identified by three unique ions. SAMPLE REQUIREMENTS.--Water collected in vials placed in stainless steel VOC sampler. Hydrochloric acid is used for preservation. Chilled at 4oC (packed in ice). CONTAINER REQUIREMENTS.--40 milliliter baked amber septum glass vial, from OCALA Quality Water Service Unit. PCODE.--The EPA/USGS parameter code. COMPOUND NAME.--IUPAC nomenclature. MRL.--Minimum reporting level..

STREAMBED SEDIMENTS

TABLE 6.--Delaware River Basin NAWQA project site descriptions. REMARKS.--The following table lists sites at which stream bed sediments were collected during calendar year 2000. The location of the stream gage is described if one is present at the site. Samples were collected throughout a section within several hundred meters upstream and (or) downstream of the stream gage, unless stated otherwise in the description. Streambed sediment samples were collected during low-flow conditions during June and July 2000 to determine concentrations of trace elements and hydrophobic organic compounds. Bed sediment samples at each site were composites of the top 1-2 centimeters of material from at least five different depositional areas within the stream reach. A subsample from the composite sample collected at each site was processed for particle-size analysis. Additionally, subsamples from the composite were: (1) processed using a 2.0-millimeter stainless-steel mesh sieve for preparation of material for organic contaminant analysis, and (2) processed using a 63-micrometer nylon-cloth sieve for preparation of material for trace element analysis. Specific details describing the sediment samples can be found in Shelton and Capel, 1994, Guidelines for collecting and processing samples of streambed sediment for analysis of trace elements and organic contaminants for the National Water-Quality Assessment program: U.S. Geological Survey Open-File Report 94-458, 20 p.

ANALYSIS OF SAMPLES COLLECTED AT SPECIAL-STUDY SITES DELAWARE RIVER BASIN NAWQA PROJECT

FISH COLLECTION RESULTS--Continued

Fish-community surveys were conducted at 7 stream sites in the Delaware River basin during the 2000 water year. Sites were located in New Jersey and Pennsylvania. Fish were collected by electrofishing with pulsed-DC current in a representative 153 to 310 meter long reach at each stream site. One electrofishing pass was conducted at each reach. One-quarter inch mesh was used for the dip nets. Fish were identified, measured, weighed, and checked for anom- alies such as parasites, lesions, and skeletal deformities. Most individuals were returned to the stream after processing. More details regarding collection methods can be found in Meador and others, 1993, Methods for sampling fish communities as part of the National Water-Quality Assessment program: U.S. Geological Survey Open-File Report 93-104, 40 p. Additional surface-water and/or water-quality data for these sites can be found in the continuous record station section of this report. Family names are in uppercase, scientific names are in italics, and common names follow. Minimum and maximum total lengths (in mm) are in parenthesis below abundance.

ANALYSIS OF SAMPLES COLLECTED AT SPECIAL-STUDY SITES DELAWARE RIVER BASIN NAWQA PROJECT

CONTINUOUS WATER-TEMPERATURE DATA Continuous water-temperature data were collected at the Delaware River Basin National Water Quality Assessment synoptic sites from July 17 through September 30, 2000. These data were collected to coincide with ecological data that were being collected during that time frame at most of these sites. Each site was instrumented with an, in situ, submersible, water-temperature logger that was programmed to record every 30 minutes. Additional water-quality data for these sites can be found starting on page 496.

SURFACE WATER SYNOPTIC SAMPLING--Continued May 15 through June 27, and September 11 through October 16, 2000

Miscellaneous water-quality sites are locations where non-routine water-quality data are collected during one year for use in hydrologic analyses. Data are collected either intermitently or systematically for a limited period of time. Water-quality data presented in this table were collected by the Delaware River Basin National Water-Quality Assessment Program (NAWQA) as part of two basin-wide synoptic surveys of nutrients, pesticides, major ions, and organic carbon, during periods of base flow; the first survey was May 15 through June 27, 2000, and the second was Septermber 11 through October 16, 2000. Selected samples were analyzed for pesticides on schedule 2001 (listed with minimum reporting levels on page 463); only pesticides identified by the analyses in one or more samples are listed in the water-quality tables. Bed sediment and fish community data are available for some of these sites, and presented on pages 467-481.
